Solar X-ray flux remained below B level. There are no spotted regions on disk and Solar flaring is expected to remain below C level over the next days.

There were no Earth directed Coronal Mass Ejections (CMEs) observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels. The greater than 2 MeV electron flux was at nominal levels the past 24 hours. An increase of the electron flux may be expected following the high speed Solar wind conditions over the next days.

Solar wind was initially at background conditions with speed around 300 km/s and total magnetic field under 5nT; until 1:30UT when Solar wind conditions became enhanced. By 8UT total magnetic field even reached over 15nT, with a sustained and pronounced negative Bz of -15nT. Only in the past hour Bz eased to a more moderate -5nT. Solar wind speed has so far not climbed above 380 km/s. The phi angle saw some excursions back and forth between the negative and positive sector, but seems to have mainly switched into the positive sector. The enhanced Solar wind conditions are expected to continue over the next days, associated with a series of patchy coronal holes.

Geomagnetic conditions reached minor geomagnetic storm conditions (NOAA Kp and local K Dourbes 0-5). In the next 24 to 48 hours active conditions are expected to continue with a possibility of further minor geomagnetic storm episodes.
